Proximity sync files with bluetooth HELP

[MarkU]

Hi all.. I'm trying to automatize some things with my ming, like, a back-up of my main.db to my desktop, synchronize my mp3's and some other things.....

What I had in mind and is almost done is the following.
My linux-PC with a bluetooth dongle have a cron task that check every 2min if the phone is near the computer, then, if it is close it try to make a ppp connection ( the one used for blueFI )
Once the ppp connection is up the script start to sync, back-up, etc...

In the phone part, I have another cron task that every 6 min try to make a ppp connection.

Ok, almost everything is working, I have both cron task scripted an working, the phone is detected, PC and phone connect and I get the ppp0 device with the ip...

I can make a telnet connection an ssh connection with dropbear and explore the phone with samba and ftp.
the problem comes when I want to copy a file bigger than 50kb, the link break and the only error that I receive from pppd from both sides is

Hangup (SIGHUP)
Modem hangup

Can somebody help me with that??
If I get every-thing working I will post here all my work thanks.

Maybe you have an MTU different on both ends?
Well, my 2 cents, i don't really know

@sabrod

The MTU from both sides are equal, I have chequed with 576 that is the standar for DUN conections, and probed with 1500, the standar for Ethernet. In both case it hangs.

I have proved to limit the download speed to 1kb/s and it stil hang.... it looks like its not a speed problem.

Here are some result from some commands

From PC
#ifconfig ppp0

ppp0 Link encap:Point-to-Point Protocol

Here you can see with the ping -f that the conection suport hi load and didnt hang.

what other propierty of network can be afectin this?

here are the pppd peers files
from PC

mtu 1500

from A1200

#connect 'sleep 1; echo -n CLIENTSERVER'

I have proved with less speed, from 9600 to 912600, using and not using crtscts control.

Some idea?

ok, I get the samba server working, but no FTP an SCP, that would be easier for scripting.

I couldn't find the main problem, but with samba things seems to be ok...
When Everything work I will post the results...

I tested the battery life with the cron daemon running every 6 minutes, and its life is the same as when you have the bluetooth on (that you need for this to work)

With WiteMing1 and bluetooth on all day, and common use(2 o 3 calls/day 6-10 sms/day), battery life is 2,5 days.

PD:Sorry for the double post, but this is different from the previous one
PD2: Mods, if this thread might be in other place, move it, thanks.
